Description
SIP (Session Initiation Protocol) is used for Voice over Internet Protocol. It is defined by the IETF
(Internet Engineering Task Force) RFC3261. Other RFC designations, such as RFC 3842, refer to a
later implementation of SIP and may be supported by the IPK II depending on software revision of the
CPUII. Commonly called SIP Station, this feature is used for IP Stations using (SIP) Session Initiation
Protocol.
SIP analyzes requests from clients and retrieves responses from servers, then sets call parameters at
either end of the communication, handles call transfer, and terminates. Typically, such features,
including but not limited to Voice over IP services, are available from a SIP service provider.
Each Media Gateway 16 application can support up to 16 TDM Talk paths. This total may be shared
among SIP Station or SIP Trunks. Registered SIP Stations and/or SIP Trunks require a one-to-one
relation with the MG16 DSP Resource. This is a required component of SIP implementation in IPK II.
The Electra Elite IPK II
supports industry standard SIP (RFC 3261) communication on the WAN side, and interfaces with the
MG16 Application.
For this feature, the Media Gateway 16 is installed and assigned as a VoIP MG16 ETU. Each Media
Gateway 16 supports IP signaling for up to 16 (SIP Trunks and/or SIP Stations) and reduces the
maximum capacity of system stations and/or Trunks in accordance with the number of registered SIP
Stations.
SIP IP Stations use the PVA(X)-U10 ETU Media Gateway. The media gateway card controls and
interprets RTP messaging from the SIP IP Phone to the Elite IPK II CPUII, therefore KSU Programming
(PRG 84-05-03) Master/Slave determination is NOT required.
IP Station (SIP) – MG16
contains a regular TCP/RTP/IP stack that can handle real-time media,
